Two domain site: Link base URLs point to wrong domain
I have been running domain.co.za, but recently purchased domain.com. Both domains now point to the same Wordpress site. On domain.com pages all the links point to domain.co.za and on domain.co.za all the links point to domain.com, so it flip-flops between the two domains.
I am wanting both domain.co.za and domain.com links to point to domain.com.
I have set the site address to domain.com, but I have had to leave the WordPress address at domain.co.za otherwise I can't log in.
Any help to get all links to point to domain.com and stop the flip=flopping would be appreciated.
www.puresweetjoy.co.za and www.puresweetjoy.com | The problem turned out to be that my hosting company had copied domain.co.za to domain.com rather than pointing both domains to the same installation. I was able to update the site URL of domain.co.za to domain.com so all of its links went to domain.com, but I couldn't log in to domain.com so all of its links pointed to domain.co.za, causing the flip flopping. It was my (bad) assumption that I only had one site running. | stackexchange-wordpress | {

How to get current site id? (WPMU)
I am using WordPress with MU activated. I found a function here that supposed to return an object with the current side ID. But it's returning 1 for all websites.
<?php get_current_site(); ?> | You're right, `get_current_site()->blog_id` will return 1, as it refers to the network.

Display assigned terms with link
I want to display product assigned terms, wrapped in link/anchor MarkUp, in my sidebar on a page as a widget. I am not getting the correct tag URL. Code returns visited product URL instead of listed tags URL.

$custom_terms = get_the_terms( 0, 'product_tag' );
if ( $custom_terms ) {

Remove a Plugin function through theme's function.php?
I am using a Plugin called PixGridder for backend setup, but i dont want the front-end css to apply.. I found that in the plugins functions.php has these lines:
public function front_styles() {
$theme_style = get_stylesheet_directory().'/gridder.css';
if (file_exists($theme_style)) {
wp_enqueue_style( $this->plugin_slug, get_stylesheet_directory_uri().'/gridder.css', array(), $this->version );
} else {
wp_enqueue_style( $this->plugin_slug, PIXGRIDDER_URL.'css/front-gridder.css', array(), $this->version );
}
}
add_action( 'wp_enqueue_scripts', array( &$this, 'front_styles' ) );
My question is, how do i unregister this function? or at least prevent the plugin from looking for the front styles though my Theme functions? - and is it even possible to unregister a function through a theme?
Thanks. | Same way you would remove it from anywhere else, be it a plugin or theme or whatever.

Multisite main theme changes do not show up in child sites
I have googled and not found an answer so maybe this is too basic. I have a main site for a school blog, and will create a child site for each classroom. I want each site to use the same basic template which is network-enabled.
When I add a header to the theme (as a super-admin), I expected the change to show up in the child sites since they use the same theme.
Using the above task as an example, do I really need to go to each child site and add the header separately? Do I instead need to create a child theme in the main site? In general, do any changes in the main theme show up automatically in the child sites? | In a multisite Installation each site is a single blog. It has its own contents and settings.

4.0 remove_filter for Wordpress core function not working for me
I was trying to overwrite how captions are embedded into a page when editing in the admin. I simply did this:
remove_filter( 'image_send_to_editor', 'image_add_caption', 20);
add_filter( 'image_send_to_editor', 'update_image_add_caption', 10, 8 );
But it's just not working. I have tried different variations of priorities, and not using them at all, but it doesn't work. Why wouldn't this work?
**UPDATE**
Here's what I am trying right now, but `$result` always returns false, so the filter isn't removed.
function childtheme_remove_filters(){
$result = remove_filter( 'image_send_to_editor', 'image_add_caption', 20);
add_filter( 'image_send_to_editor', 'update_image_add_caption', 20, 8 );
}
add_action( 'init', 'childtheme_remove_filters' ); | From the comments the `remove_filter` is called too early before the core `add_filter` is called. Best way to avoid this is to always remove nd add your filter at the init action
add_action('init','wpse163434_init');
function wpse163434_init() {
remove_filter.....
add_filter.....
}
This way you are assure that the core had finished initializing and all the core actions and filters are already set.
**Update:** all of the above is nice and true, but there is no software without bugs and apparently some filters are added in places where it is really hard to remove them without feeling it is too much off a hack, and `image_send_to_editor` is one of them.
Luckily that filter applies the `image_add_caption_shortcode` filter and passes the original html to it so instead of removing `image_send_to_editor` you might get the same impact by using the `image_add_caption_shortcode` filter. | stackexchange-wordpress | {

Where does the locale come from?
I have currently the problem that I don't understand where the locale that is set in the header of the rendered blog comes from. The header for each post (and all other pages) looks like:
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
...
I tried to find the way to influence the second line `<html lang="en-US">` but could not find it. I tried the following:
* Searched in the settings of WordPress site, if the admin can change the default locale, but could not find it.
* Used different browsers, and changed in all browsers the language to German.
My code to read the locale is:
$loc = get_locale();
The documentation for that function reads:
Return Values
(string)
The locale of the blog or from the 'locale' hook.
So where can I set the locate in the administration of my Wordpress site, or is there an option to use the locale of the browser? | Locale comes from WPLANG constant defined in wp-config.php. In the last version of Wordpress (4.0, maybe 3.9) something is changing. You can install more languages setting WPLANG to different locale. Then you can select the language in the backend from Settings > General > Site language and set locale in the header.

Add custom fields to existing posts (admin pages)
I'm able to add a custom field for new posts (in the admin pages), using the action hook `wp_insert_post`. But I would like to add the custom field for old posts, when I am editing the post (in the admin pages), there is any action hook to do that ?
Sample code that I'm using:
/**
* Default custom field for Municipi
* @param [type] $post_ID [description]
*/
function set_default_custom_field_municipi($post_ID){
$municipi = get_post_meta($post_ID,'municipi',true);
$default_meta = ''; // value
add_post_meta($post_ID,'municipi',$default_meta,true);
return $post_ID;
}
/** add custom fields by default */
add_action('wp_insert_post','set_default_custom_field_municipi');
Thanks in advance, | As Andreas Krischer suggested, I fixed using an script to update all the old values and then only using the `wp_insert_post` to create the custom field for the new posts.
The script that I used:
INSERT INTO wp_postmeta( post_id, meta_key, meta_value )
SELECT wp_posts.ID, 'municipi', ''
FROM wp_posts
WHERE wp_posts.post_status = 'publish'
AND wp_posts.post_type = 'post'

How to only show posts on last child category
By default WordPress will list posts on each category in its hierarchy.
Example:
Parent
/- child
/-- grandchild
When viewing the "Parent" category you will see a list of posts from child, grandchild and parent - even if the post is just ticked in "Grandchild".
My question is: How do I only show posts when viewing the last child? Is there a built in WordPress function for this?
e.g.:
[grandchild categories] = array of grandchildren
if(in_array( [grandchild categories] )) : show posts
else:
do nothing | There is of course the `include_children` parameter for `WP_Query` as part of the taxonomy parameters. Which I suppose should work like this for you:
$args = array(
'tax_query' => array(
array(
'include_children' => false
),
),
);
$query = new WP_Query( $args );
Or via `parse_tax_query` for your category archive:
add_filter(
'parse_tax_query',
'wpse163572_do_not_include_children_in_category_archive_parse_tax_query'
);
function wpse163572_do_not_include_children_in_category_archive_parse_tax_query( $query ) {
if (
! is_admin()
&& $query->is_main_query()
&& $query->is_category()
) {
// as seen here:
$query->tax_query->queries[0]['include_children'] = 0;
}
}

What is the difference between wp_strip_all_tags and wp_filter_nohtml_kses?
Taken from the articles referenced below:
wp_strip_all_tags()
"Properly strip all HTML tags including script and style."
wp_filter_nohtml_kses()
"Strips all of the HTML in the content."
Ref:
* <
* <
These functions _appear_ to serve the exact same purpose. How are they different? | The wp_strip_all_tags() function will remove all HTML, including the content of script and style tags.
The PHP strip_tags() function largely does the same thing, except it won't eliminate the content of script and style tags. WP's wp_strip_all_tags() function uses this after eliminating the scripts and styles manually.
The wp_filter_nohtml_kses() function uses kses to remove all HTML. The main difference is the engine used for parsing the HTML. PHP's strip_tags() doesn't deal particularly well with broken or intentionally malformed HTML, because it doesn't perform any validation of the HTML. The kses engine attempts to handle malformed HTML in a better way, but it is also not a fully complete HTML parser. It is also much slower.
The wp_strip_all_tags() function is generally preferred. It's good enough for the majority of cases. The kses version is mostly included for completeness, but may be useful if you're dealing with particularly badly formed HTML. | stackexchange-wordpress | {

Although I've done some searches on Google, I have not found an answer to this question: Is there a way to check if a post belongs to a category that has only 1 posts (is the only one in its category)? I need to perform this check on `single.php`.
if ( 'the_magic_check' ) {
// do something
}
Thanks! | Use `get_the_category` to get the categories belonging to the post. You can then use `$category->count` to return the amount of posts for specific category attached to the post
Example:
If a post has just one category attached to it, you can do the following
$category = get_the_category();
echo $category[0]->count;
In your check to see if there is only one post in the specific category and then do something, you can try
if( 1 == $category[0]->count ) {
// Do something if the category has one post only

How to make blog post entries appear as input form instead of just text?

How to Set Taxonomy Object Description?
I noticed when dealing with Post Type Objects (Using `get_post_type_object();`) and Taxonomy Objects (Using `get_taxonomy();`) there's a property called "description".
How do you set this description property for Taxonomy Objects?
I don't see an option for it in `register_taxonomy();`, but I do see an option for it in `register_post_type();`. | > I don't see an option for it in `register_taxonomy()`
It's not in Codex, but is fully supported:
add_action( 'init', function() {
register_taxonomy(
'foo',
'post',
array(
'description' => 'Hi there!'
)
);
$foo = get_taxonomy( 'foo' );
echo $foo->description; // output "Hi there!"

Are post ID's reliable?
I understand that post ID's are unique, but are they _reliable_ as persistent data ID's?
More specifically, is there a guarantee that, through a migration or another data exchange, post ID's will not change?
I understand wordpress is primarily implemented using MySQL, so ID's are governed by the `AUTO_INCREMENT` mechanism; however, is there any caveat on Wordpress' end that would change this behavior in the future, or potentially with another persistence implementation (such as MongoDB)? | The pedantic answer is NO.
While IDs are unique they can change without any change in UX as long as the change retains the consistency of the DB. And while creating a new post will generate a new unique ID, you can also create a post via code to reuse some "old" ID.
In practice they are reliable, but if reliability is very important to you then you need to attach some data to the post which will be used as the reliable identifier for your own needs.
**Update:** totally forgot about it because it is rarely used, and most of the time I seen it used it was used incorrectly, but wordpress has a reliable unique identifier by definition and it is the GUID | stackexchange-wordpress | {

Sort custom taxonomy terms order by both count and name
I am working on a custom taxonomy sorting to make popular terms. The requirement is to sort by popular posts by post count and also I need to sort terms by name to get it alphabetical order.
Here is my code
$args = array(
'hide_empty' => 0 ,
'orderby' => 'count',
'orderby' => 'name',
'parent'=> $cat_main->term_id
);
$terms = get_terms('question_type',$args);
Another condition is that `orderby` `count` has to be `DESC` and `orderby` name has to be 'ASC'
Any suggestions? | This won't be possible via the function itself or to be exact by just providing parameters/arguments. You have to do this via hooks to alter the default behavior, I think. You should take a closer look at at least two, they are: `get_terms_orderby` and/or `terms_clauses`. | stackexchange-wordpress | {

Translating my custom theme, always translated version?
I have a custom theme which is in Dutch and now i am trying to translate the theme into english. For this i am using poedit, and converted some theme strings into _e('string-is-here')
I save both en_US.po and en_US.mo into my-theme/languages and add this to functions.php
function theme_init(){
load_theme_textdomain('my-theme', get_template_directory() . '/languages');
}
add_action ('init', 'theme_init');
to test it i edit wp-config.php by
define('WPLANG', 'en_US');
And i thought it was working, but when i changed WP_LANG back to
define('WPLANG', '');
The translated strings are always shown???
What am i overlooking?
regards | You are making wrong assumption here. `define('WPLANG', '');` doesn't mean "original locale of the string" or anything like that, it is taken literally as "no locale specified".
And when it's nothing WP proceeds to assume default locale, which is `en_US`. This is why as soon as you add English translations of string they are displayed for this case.
So to test your original Dutch strings properly you need to set `WPLANG` to respective Dutch locale. | stackexchange-wordpress | {

Any required callbacks to WP.com or WP.org?

Change sub-menu position of custom taxonomy
I'm adding an additional taxonomy to the Posts post-type and would like it to appear between Categories and Tags in the control panel Posts sub-menu.

How to display tag cloud without links

'<ul><li>'
);
where we strip all the HTML tags from the output, except the `ul` and `li` tags.
Notice that we added the `echo=0` parameter as mentioned in the Codex as a way to return the output. We could also have used `echo=` because it has to full fill the condition:
if ( 'array' == $args['format'] || empty($args['echo']) )
to return the output. So `empty( null )` and `empty( '' )` is `true` but it's strange that `empty( 0 )` is also `true`, but that's just how the `empty()` function works ;-)
The `wp_tag_cloud()` function has the `link` parameter, but it only has the possible values as _view_ or _edit_. It would be nice to have the _none_ option, to disable links and show only the text. | stackexchange-wordpress | {

the_content() behavior on attachment.php versus single.php
I'm having some trouble getting `the_content()` to work on attachment.php. I have a template page that has the basic loop and simple calls `the_content()` in the loop to display the post.
## Scenario 1
Load an attachment page with the template file `single.php` and it will output the image tag and run it through `prepend_attachment`.
## Scenario 2
Load an attachment page with the template file `attachment.php` and it will output nothing from `the_content()`. I've also verified that it doesn't called the prepend_attachment or the_content filters.
Can someone explain what is going on here?
<?php
if (have_posts()) : while (have_posts()) : the_post();
the_content();
endwhile; endif;
?> | This is correct behavior, if your attachment doesn't actually have anything in `post_content` field (which is quite common).
When post–centric templates run, `prepend_attachment()` is used as filter to "emulate" post content. This is not the case with template "intended" for attachments.
If you look at `template-loader.php`:
elseif ( is_attachment() && $template = get_attachment_template() ) :
remove_filter('the_content', 'prepend_attachment');
the filter is explicitly removed.
So there is no "fake" content generated for you. You will have to decide and express in code what do you actually want shown for attachments, or simply add back the filter if _that_ is what you want. | stackexchange-wordpress | {

Wordpress showing wrong category name
I'm using:
$category = get_the_category();
echo $category[0]->cat_name;
to display the current category as a header in an archive template (example of local url is < < etc)
For the first 3 categories, this works fine, but after that it's showing a child category instead. I've tried changing the slug of the posts _and_ the category, updating the permalinks, unpublishing posts in the child category which is showing (it then shows another child category instead) - but none of this solves the problem.
I suppose it's a clash of slugs & permalinks somewhere, but changing these doesn't seem to fix it. Is there more specific wordpress php which can be written to avoid this clashing?
I did find this post: Archived Posts in Wrong Category but it doesn't seem to be the same problem.
Thanks | As far a I can understand you need to display the category name for the current page when viewing a category page.
You can make use of the query variables to retrieve the category name, for example:
$category = get_queried_object('cat');
echo $category->name;
**EDIT**
A global check to see what is returned by the main query for a specific page/template, you can do a `var_dump` of the main query global, `$wp_query`. Add the following code inside your template outside of the loop
?><pre><?php var_dump($wp_query); ?></pre><?php
To check which query variables are available on a template/page, you can do a `var_dump` of `get_queried_object()`

Getting the parent terms adds additional empty markup

foreach ($cities as $city) { ?>
<li><a href="<?php echo get_term_link( $city, 'city' ); ?>" class="button radius"><?php echo $city->name; ?></a><li>

<li>
</li>
<li> ... correct data about term 2 </li>

check if the user is owner of current page

Create page using same slug as custom post type
I am working on a site for a client who has custom post type called "practitioners" and several posts within this displaying info related to different practitioners. I want to create a page with a slug "practitioners/page-name" but of course the site wont let me use this as a slug.

Any ideas?

Use a Wordpress Plugin in non-Wordpress .php page
I have a website consisting of html pages but with one blog page in Wordpress. There is a news ticker plugin on this wp page which I would like to embed into the other pages of the site.
How can this be done?
Many thanks in advance. | Well...outside of the fact that you're unable to load PHP in *.html files, let's try to look at this from a different angle here...
One way that this could be done would be to convert all of the *.html pages - that you would like to include the news ticker on - to *.php pages, and to insert a PHP function that loads WordPress in the header of those files, along with the news ticker shortcode or display function.
Another way that this could be done would be to create one .php file in the root of your WordPress installation that only includes the aforementioned PHP function that loads WordPress in the header of that one file, along with the news ticker shortcode or display function, and loading that on the html pages through an iFrame.

Using a Single Custom Post Type Template for Multiple CPTs
I'm working on a major WordPress site and ran into a problem where I need to use multiple custom post types, but I only want to use one template for all of them.
I found a code by Brad Dalton of WPSites that works with a single CPT name. Looking for a solution that allows multiple CPTs. Source: <
What I want is the ability to use cpt-1, cpt-2, cpt-3. I'm not a PHP coder, not quite sure how to make this an array that will work in my functions.php
BTW, I wish there was a `is_post_type_single` like there is a `is_post_type_archive`. Would be much easier to default to all CPT Single templates.
Editing Reasons: Removed Brad's code to respect his copyright. Added link to source. | Doesn't exist any `is_post_type_single` function, because there is no need for it.
`is_singular()` fit perfectly your purpose.
Example code using `'template_include'` filter:
add_filter( 'template_include', function( $template ) {
if ( is_singular( array( 'cpt-1', 'cpt-2', 'cpt-3' ) ) ) {
$locate = locate_template( 'custom-template.php', false, false );
if ( ! empty( $locate ) ) {
$template = $locate;
}
}
return $template;
});
Of course change the name of your CPTs and the name of your custom template.

Different Front page for Mobile
I want to make a different front-page and show it to the mobile user, instead of the one used on desktop.

PS. I looked into `wp_is_mobile()` but that seems to send mobile user to a URL you specify. What I actually need is that user should land (and remain) on www.domain.com, but instead of the desktop-front-page, the mobile-front-page should be served. | Switching the actual template file could work in the same way as above using `get_template_part()`.

} else { // If it is not a mobile device
get_template_part( 'desktop-front', 'page' );
} // end wp_is_mobile()
To take this a step further...

Adding a filter with custom function to the menu / navigation

$classes []= "laden-1";
}
}
return $classes;
}
First I check, if the post type is "marke" After that I check, if the "marke" has the characteristics "laden-1" at the taxonomy "laden".
After about three hours I think, that there is a problem with the function "has_term", It seems that this function is not called correctly.
Does anybody has a suggestion?
Many many thanks in advance | I'm not sure how you're settings up your menus but this is probably the most reliable method.
function auto_custom_type_class( $classes, $item ) {
$type = get_post_type( $item->object_id );

$classes []= "laden-1";
}
return $classes;
}
add_filter('nav_menu_css_class', 'auto_custom_type_class', 10, 2 );
The problem with your code is that `$item->ID` refers the to the navigational items ID instead of the actual post ID which is found at `$item->object_id`.

Can you change the main heading of a page in the WordPress admin (without output buffering or JavaScript)?
I'd like to change the heading text on an edit page—this bit:

From what I can tell, core is just echoing `$post_type_object->labels->name` \- is there any way to filter that output? I can't find anything, but I may be looking in the wrong places.

//

What the code does is caste the value returned by `get_option()` to an array. It is being done so that `array_merge()` works correctly and doesn't trigger warnings/errors. That much is pure PHP and is off-topic.

When and Where is `global $post` Set and Available?

before `template_redirect` action
after `plugins_loaded`
So my question is, what's the earliest I have access to `global $post`? | Global `$post` var is set by `WP::register_globals()` method.
It is called by `WP::main()` method, on its turn called by `wp()` function that is called when `wp-blog-header.php` is loaded.

Post slugs and images cannot have same name?
If I go to Media Library and upload an image called `apple-pie.jpg`
And then I create a post called `www.domain.com/apple-pie/` The link does NOT take me to the post. Instead the link will take me to a page displaying the media (In other words, it uses a page template instead of single.php)

If your file was named something else, there would not be any conflicts.
If you have your post permalinks set to `/%postname%/` , and you upload an image FIRST, and then create a post SECOND, then WordPress has to make a choice between the two when someone tries to access the Permalink.

Where does wordpress store the FTP credentials?
When wordpress asks for FTP information to upgrade, you type it in and then it seems to store it for future use (for future upgrades, and maybe also for media uploads?)
Where does it store these details? Is it in a file? In the database?
I'm trying to figure out what information is being used to access the server.
Tried grep-ing for `ftp` in the php files and didnt see anything. This also doesn't seem to be a setting that is exposed in the admin interface.
Thanks! | It doesn't. WP Filesystem API will ask for FTP credentials, but it will do so for each operation. They aren't stored persistently.
They _can_ be stored persistently by hardcoding into `wp-config.php`, but WP won't do that itself, it's a user action.
Note that WP only asks for FTP credentials _if_ it cannot modify files without them. If specific setup used to ask for them and stopped then likely the server configuration or file permissions had changed and now allow WP to manipulate files without going through FTP. | stackexchange-wordpress | {

How to check if a user exists by a given id
Is there any way to check if a user id exists? I want to create a function similar to `username_exists()` but which returns if the id exists or not. | Use this function:
function user_id_exists($user){
global $wpdb;
$count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) FROM $wpdb->users WHERE ID = %d", $user));
if($count == 1){ return true; }else{ return false; }

if(user_id_exists(1)){
//it does exists

//it doesn't

Shortcode from admin textarea to page
I've added shortcode to a page via a custom textarea in my Wordpress admin, but the shortcode is seen as text and gets wrapped in quotation marks, so it doesn't work.

This is basically how I sanitize my input:
if( isset( $input['textarea_input'] ) )
$new_input['textarea_input'] = sanitize_text_field( $input['textarea_input'] );
This is how I output it on the page:
<?php echo $options['textarea_input']; ?>
do_shortcode does not change anything
<?php echo do_shortcode($options['textarea_input']); ?>
My guess is that the Wordpress TinyMCE editor recognizes shortcode, and therefor it works. Since mine is added via a hidden text area, it's just seen as plain text. What is going wrong here? | Your sort of right, the Wordpress editor saves content thru a filter called the_content.

Adding menu_order to CPT admin page

Customizer: Unique identifier that distinguishes which image upload control is uploading an image
In the Theme Customizer, I've got a custom `add_action('wp_handle_upload', 'upscale_responsive_bg_imgs')` which upscales responsive background images when uploaded from the theme customizer.

Confused about how to use wp_enqueue_style
I've read the updated codex about using `wp_enqueue_style` instead of `@import`. I'm a newb and just flat out confused how to use this.

wp_enqueue_style( 'athletica-style', get_template_directory_uri().'/style.css' );
wp_enqueue_style( 'child-style', get_stylesheet_uri(), array('athletica-style') );
}
Also, I've seen warnings about if your parent themes use `wp_enqueue_style` in it's functions.php file. Mine does!
Now what do I do? | wp_enqueue_style is a MUST to add your styles according to codex. But you don't need to use your child or parent theme name anywhere.
<?php wp_enqueue_style( $handle, $src, $deps, $ver, $media ); ?>
The first param $handle could be anything, doesn't matter what you put here. I can see you have used your theme name in there, it acts as an identifier so you can use anything. But, make sure they are unique in all cases. For example, if you use like:
wp_enqueue_style( 'athletica-style', get_template_directory_uri().'/style.css' );
wp_enqueue_style( 'athletica-style', get_stylesheet_uri(), array('athletica-style') );
Here the handles are same, so you will see one of those css is added, not both.
I think you are familiar with other parameters of this function.
Note: It is not mandatory, but always a good practice to register the style using `wp_register_style` function. | stackexchange-wordpress | {

Don't load scripts if on mobile/tablet
Would like to ask the question is it possible to stop the laoding of some scripts when viewed on a mobile/tablet device ?
In the theme functions file you have `wp_enqueue_script(...)`. How would you go about loading if based on device/screen size..
Is this possible? | `wp_is_mobile()` does not really solve your problem completely. To be honest here, there is no logic in Wordpress to achieve what you want
* First of all, `wp_is_mobile()` only checks for mobile devices. Tablets are excluded from this
* Window sizes are determined on browser side, not server side, so there are no way for php to check window size. That is why there are also no function in Wordpress that can detect a window size
The only probable way to do this is to make use of javascript. I've seen examples where javascript is used to determine window size and then do load something accordingly.
